To all whom it may concern:

Be it known that I, HARRY PALEY, a citizen of the United States, andresident of Millie, county ofNorfolk, State of Massachusetts, haveinvented an Improvement in Apparatus for Feeding Roll-Mnsic, of whichthe following description, in connection with the accompanyingdrawings,is a specification, like characters on the drawings repre senting likeparts in each of the several views. i 4

This invention relates to mechanism for feeding music, which is printedon asingle strip or ribbon of paper, in contradistinction to m-usic asmost commonly printed on separate sheets which are arranged inbook form,my present improvement being specially valuable and convenient for usewith pianos, organs and the like instruments, which are played with bothhands. In carrying my inventlon into practical effect I print themusicin blocks which are substan tially the same as the pages ofgsheet musicas commonly published but, instead-ofprinting each page or block on aseparate sheet of paper, Iuse a continuous strip or ribbon of paper, andI place the pages or blocks in proper sequence so that the ribbon may bemounted upon Irollersand then manipulated, after the manner of apanorama, by means of automatically actuated mechanismwhich may becontrolled, by a single movementof one hand or a foot of the musician,thus feedingthe sheet along laterally with an ins termittent movementwhich brings each successive page or block of the music into view asneeded. y i j The foregoing and other objects and ad vantages of theinvention will more fully appear from the, following detaileddescription, and the distinctive features of novelty will be pointed outin the appended claims.

Referring to the drawings:

Fig. 8 is a relatively enlarged view of one of the rolls upon which themusic is wound, intermediate portions thereof being broken away;

Fig. 4 is an elevation of a sprocket wheel with which the roll of Fig. 3is engaged for actuation when the device is assembled ready for use;

In these drawings th'e numeral indihousing in the side portions of whichare located vertical rolls 11 .and. 12,the upper end of each of saidrolls being :journaled in a suitable bearing in the housing, as seen inFig. 1. The lower end of roll 11 is secured to or stepped in a sprocketroll 13 and the lower end of the roll 12 is likewise stepped in asprocket roll 14, andthe said rolls 13, 1 1 are engaged, and driven (asI will explain hereinafter), by means of a sprocket upon the roll 11,which may be termed the delivery roll, andthe free end of said paper isattached to the roll, 12,

which is to serve as the take-up roll, the arrangement of the describedparts being such that when the rolls 11, 12 are rotated intermittently,the pages of the music printed upon the strip of paper are successivelyexposed to View in the front opening of housing 10. By having the endsof the rolls 11, I12 stepped or socket-ed in the respective sprocketrolls 13, 1 k as described, it is possible to remove the rolls 11, 12and to interchange them with respect to the sprocket rolls 13, 14 sothatthe music sheet thereon may be run back without re-winding thereof andthus it is possible to have the music printed on both sides ofthepaperstrip or web. The rolls 11, 12 hearing thepaper strip beingremovable it is possible to sub,- stitute different pairs of rollsbearing different series of songs or other musical notations at will. Inorder to thusfeed the paper along I have provided simple and reasonablycheap. mechanism which I will Mounted between the opposite sides of thesprocket belt 15 is a barrel 16 in which is a coiled spring 17 one ofwhose ends is secured to the said barrel, its other end being secured toa fixed arbor 18. The outer, circumferential, face of barrel 16 isprovided with radial pins 19 which are adapted to engage the openings inthe belt 15 in such manner that, when the barrel is rotated, the beltwill be started into action and will rotate the sprocket rolls 1.3, 1.4;and the connected rolls 11., 12.

Mounted fixedly on the arbor 18, at the under side or base of barrel 16,is a ratchet disk 20 which is engaged by a pawl 21 that is mounted uponthe barrel and serves to prevent the accidental unwinding of the coiledspring 17. The barrel 16 is loosely mounted upon a fixed base 16 whichis formed with a lateral extension 16 which serves as a bracket by meansof which the base may be secured to the back side of the housing 10. Thesprocket belt 15 is provided with one or more openings 22 which areengaged normally to the free end portion of a stop lever 23 which ispivotedin bearings 24 formed on the lower face of the base 16*; theother end portion of said stop lever being formed as a push button 25 bymeans of which the lever 23 may be rocked in order to withdraw the upperend of said lever from the opening 22 and so that the barrel may berotated 011 the arbor. Lever 23 is held normally in its operativeposition by means of a spring 26, as will be understood by reference toFig. 7 of the drawings. Screwed fixedly into the lowerend of the arbor18 is a milled thumb piece 27 by means of which the arbor may beconveniently rotated whenever it is desired to wind up the spring 17.

Assuming that the strip of music paper has been coiled upon the roll 11,with its free end attached to the roll 12, and it is desired to feed thepaper along so as to expose to view the next block of music, it is onlynecessary to push the button 25 with a quick movement and then releaseit. The upper end of the stop lever is thereby withdrawn from theopening 22, thus permitting the spring 17 to start the barrel inrevolution and thereby'moving the belt 15 and rotating the rolls 11 and12 sufficiently to feed the music paper forward. Meanwhile the end ofthe stop lever rests upon the rotating barrel 16 until the opening 22comes into register again with the end of said lever which then entersthe opening 22 and thus stops the barrel and its connected movableparts. It will be understood that, by simply pushing the thumb-piece 25,the several pages or blocks of music may be successively brought intoview. Though I have herein shown the stop device as controlled by athumb piece 25 it is to be understood that in a broader aspect this ismerely illustrative and intended to typify any suitable manuallycontrolled device which may be either hand operated or foot operated.

Having described my invention, what I claim as new, and desire to secureby Letters Patent is:

1. Apparatus for exhibiting and feeding intermittently a music paper orlike web, comprising a pair of rolls, one constituting a delivery rolland the other a take-up roll, a sprocket belt engaged with said rolls, amotor unit consisting in a barrel equipped with sprocket teeth engagingsaid belt with a spring housed therein, and a manually controlled deviceengaging said belt to control the movement of the paper sheet by saidmotor unit for presenting a series of songs or like subjectssuccessively.

2. Apparatus for exhibiting and feeding intermittently a music paper orlike strip consisting in a pair of rolls constituting a delivery rolland a take-up roll respectively, driving means to which said rolls aredetachably fitted whereby they may be interchanged for the purposestated, said driving means consisting in a sprocket belt en- .gaged withsprocket rolls, and a motor unit consisting in a barrel having sprocketpins projecting therefrom to engage said belt, a spring housed in saidbarrel, and a manually controlled stop device arranged to engage saidsprocket belt to limit the movement thereof for presenting a series ofsongs or like subjects successively to view.

3. Apparatus for exhibiting and feeding intermittently a music paper orlike strip consistingin a pair of rolls holding the strip between themfor horizontal movement, operating means for said rolls detachablyengaged therewith comprising a sprocket belt, a motor drum engageddirectly with said belt, and means engaging said belt for permittingpredetermined manually controlled movements of said rolls for successiveexhibition of subjects on said paper strip.

In testimony whereof, I have signed my name to this specification.

HARRY PALEY.
